Lastly, if you constantly see this warning despite confirming proper pressure in all 4 tires plus your spare (Yes, there is a sensor there as well) Here are steps to follow to disable the warning light:
Keep in mind, tire pressure does, in fact, change in different weather conditions, therefore, you should ask your mechanic or dealer about the levels for dissimilar temperatures. You can locate the manufacturer’s recommended tire pressure on the inside of the driver’s door. The EVIC even indicates which tire has low pressure. The warning low-pressure indicator light which appears within your dashboard or via the EVIC, indicated by a chime, should turn off automatically after your tires receive the proper amount of air pressure/ PSI. Turn the ignition on and ensure that the DEF level gauge is reading correctly.Ħ8192659AC.Module kit, urea pump/level unitĦ8035704AB.Diesel exhaust fluid (1 gallon)Ħ8056278AB.Diesel exhaust fluid (2.Dodge RAMs are equipped with a TPMS (Tire Pressure Monitoring System) to assist you in maintaining the correct tire pressure. Using wiTECH, perform a DEF Reductant Doser Pump Prime Override test a total of 10 times to ensure that the DEF pump has been sufficiently primed and that all air has been purged from the pump and filter. Ensure that the DEF tank is approximately one-half full. DTCs may be present, including P203B (reductant level sensor circuit performance), P203C (diesel exhaust fluid reductant level sensor circuit low) or P203D (diesel exhaust fluid reductant level sensor circuit high). The sensor translates this signal change into a fluid level and buses the information to the IPC (instrument panel cluster) via the DCU (dosing control unit).Ī manufacturing defect in the level sensor may have occurred if built on or after April 1, 2014, and on or before Sept. As the fluid level in the tank decreases, the level sensor becomes exposed to air which alters the signal sent out by the sensor. The DEF system uses a complex radio frequency type level sensor to detect the amount of fluid present in the DEF tank. A defect may be present with the DEF (diesel exhaust fluid) level sensor.
